Vibrating Cup Mill, Pulverisette 9

The Fritsch Vibrating Cup Mill Is The Perfect Instrument For Extremely Rapid Size Reduction (Rotational Speed: Up To 1150 Rpm) Of Brittle And Very Hard Samples Dry Or In Suspension To Analytical Fineness

Method of operation
The Pulverisette 9 operates on the principle of a vibrating cup mill. The rotating flyweight makes the grinding set; clamped on a spring-loaded system, vibrate horizontally. As a result of the centrifugal force created, the tumbling movement accelerates the grinding elements (puck and rings), which make up the grinding set. The sample is ground by the impact and friction effect.

The Pulverisette 9 is the only vibrating cup mill in the world with frequency transformer control that fulfills all relevant safety standard worldwide. With this, the vibrating frequency of the load (grinding set and sample) can be adjusted so that grinding takes place in the shortest possible time, optimizing energy consumption.

In the Vibrating Cup Mill, the grinding is performed by horizontal circular oscillations of the grinding set on a vibrating plate. The grinding set consisting of ring and puck comminute the grinding sample with extremely high pressure, impact forces and friction. In this form of grinding, the transmission of forces onto the grinding sample is much more important than the pure motor power. A special motor is equipped with an especially interference-resistant, torque-optimized frequency converter and fulfils all the relevant safety standards worldwide. It ensures that the motor output is precisely matched to the grinding material and grinding set – which optimizes the energy consumption.
